Heritage Audio HA73EQ Elite Series Microphone Preamplifier with Equalizer

Heritage Audio's Elite Series brings their 1073-inspired preamp design to an affordable price point. Warm up any source with 80 dB of fat gain and 3-band EQ.

Manufactured in the same Spanish facilities as the rest of the Heritage Audio line of products, the Elite Series HA-73EQ is a feature-packed mic preamplifier.

After almost 7 years making one of the finest high-end outboard gear lines in the industry, Heritage Audio is proud to introduce the Elite series.

Leveraging the expertise and reputation obtained with its former hand wired, extremely time-consuming hand soldered series, Heritage is able to offer a zero compromise, high quality yet very affordable alternative to the growing number of entry-level brands.

A combination of mass production, lean manufacturing and modern construction techniques minimizes hand labor and its high associated costs when manufacturing takes place in Western Europe. By passing the savings straight into the end users´ pockets, Heritage Audio releases the most affordable outboard preamps and equalizers in its class to date.
Key components to obtain a true vintage sound are, like the industry standard Carnhill transformers, hand wound in St Ives, England.

"Amazing Sounding Mic Pre - HA-73EQ"

Overall: 4.5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Wanted to purchase a higher end mic-pre. Typically use the on-board interface preamps or my midas XL47 via ADAT. The HA-73EQ is at miles ahead for the sound. Only used on guitar and vocals and it the has more beef, girth compared the shallow sounding interface mic-pres. Build is good, but the buttons and knobs feel a little loose, but sound it great.
